Title: Safety belt retractor equipped with belt tensionner acting on belt reel
Inventor: EBNER RALF
IPC: B60R22/46
Filed: 1997-03-19
Abstract: PROBLEM TO BE SOLVED: To provide a safety belt retractor which is capable of mitigating the impact on the occupant and belt by immediately letting out a little section of belt even if the occupant suddenly bends down forward without having a time lag from the moment at which the belt is tightened by a belt tensionner to the moment at which the belt reel is unlocked. SOLUTION: When a belt (14) is to be tightened by a belt tensionner, rotation is transmitted from a traction cable (18) through a first connection mechanism (22 and 24), a cylindrical ring (32a) and a torsion bar (30) to a belt reel (12) to take up the slack of the belt. In this case, with the aid of the reaction of the belt, the reel, the torsion bar froming the shaft of the reel and an inner ring (32) of a second connection mechanism elastically attached to the end of the torsion bar are pulled up the let the teeth of the inner ring engage with the teeth of an outer ring (40). Since the first connection mechanism and the second connection mechanism are being engaged with each other, when a force is applied to the belt in the letting-out direction, the torsion bar (30) is twisted in result so that impact is absorbed.

Title: Herbicide composition for paddy field
Inventor: MUKODA HIDEJI
IPC: A01N47/16
Filed: 1990-03-19
Abstract: PURPOSE:To provide a herbicide capable of controlling barnyard grass in a low amount by compounding S-(1-methyl-1-phenylethyl)piperidine-1-carbothioate, a specific sulfonium urea herbicide and a specified phenoxyphenoxy herbicide. CONSTITUTION:The subject composition capable of selectively controlling barnyard grass contains compounds of formulas I, II and III in a weight ratio of 1:0.003-0.07:0.03-0.3. The composition exhibits a high herbicidal activity to the barnyard grass in such an amount that each of the compounds can singly control the grass, and never gives any chemical damage to paddy rice. The treatment of paddy fields with the composition until the early time (until approximately 10 days after the transplantation of the paddy rice) of weed generation permits to obtain the highest effect. The composition further maintains the herbicidal activity for a long period of time and does not admit the post-generation of the barnyard grass until the harvesting time of paddy rice.

Title: Production of grain-oriented silicon steel sheet having extremely low iron loss
Inventor: KOUHOU HIROSHI
IPC: C21D8/12
Filed: 1984-04-06
Abstract: PURPOSE:To decrease considerably the iron loss value of a silicon steel sheet without deteriorating the magnetic flux density thereof by subjecting a hot rolled silicon steel sheet to annealing within a specific temp. range and >=2 passes of cold rolling including local strain working and performing final cold rolling in a specific temp. range. CONSTITUTION:A silicon steel sheet annealed uniformly at 800-1,000 deg.C is subjected to local strain working at about 2-15mm. intervals with about <=1mm. width by rolls having projections after cold rolling and is then annealed at 600-1,000 deg.C to form coarse crystal grains in the strain worked part and to make the volumetric ratio thereof to about 5-20%. Such annealed sheet is cold rolled. The final cold rolling is performed at 100-500 deg.C to make the coarse crystal part formed by the strain working into the fine secondary recrystallization structure having good orientation as a result of secondary crystallization without the deterioration in hardness occuring in propagation of dislocation. The silicon steel sheet is therefore free from deterioration in hardness and magnetic flux density and has a min. iron loss. The strain working intervals except about 2-15mm. lead to deterioration in orientation.
